    Hmm.  I think we can at least move it into lwkt_setcpu_self()
    itself.  I must have done it originally just through paranoia.

    I'm still tracking down a network issue and don't want to 
    cvs update my tree just yet.  Could you make that change?
    (remove cpu_mb1() from after the calls to lwkt_setcpu_self()
    and add a cpu_mb1() at the end inside lwkt_setcpu_self()).
